One point is the influence of the analysis ultrafine vertical mill blade on the strengthening of the superfine grinding product. This point mainly refers to the increase in the degree of wear of the blade, the powder selection efficiency of the analysis ultrafine vertical mill will be directly affected, resulting in too much coarse powder; The influencing factors of the ultrafine vertical mill particle type introduced above mainly include the degree of wear of the grinding roller and the grinding ring, the speed of the fan of the fine mill, the speed of the main engine and the blades of the analyzer. These four factors affect the fine powder The main factors of grain size, controlling these factors during production can produce finished products that are more in line with customer needs.
